Abstract:
Objective:To explore the clinical effect of using great toe fibular flaps of both feet on reconstruction of pulp defects of two neighbouring digits.Methods:A total of 14 digit pulp defects in 7 cases were repaired in Zhoukou Huaihai Hospital using great toe fibular flaps of both feet from August 2020 to January 2023. Of the 7 cases, there were 4 males and 3 females, with an average of 28 years old, ranging from 19 to 45 years old. Meanwhile, there were 4 cases in left hand and 3 cases in right hand. There were 3 cases of digit pulp defects in index and middle fingers, 2 in middle and ring fingers, and 2 in thumb and index fingers. The area of soft tissue defect in 1.2 cm×1.5 cm-3.0 cm×2.5 cm, and flap was 1.5 cm ×1.8 cm-3.2 cm×2.8 cm. Furthermore, 1 case underwent emergency surgery and 5 were repaired in elective surgery. The donor site of the flap was closed directly, and an intermediate-thickness skin graft was prepared from the medial plantar area for transfer in the case of high suture tension at the wound edge. After surgery, patients received postoperative by outpatient clinic and WeChat to observe the appearance, sensation, functional recovery and flap contracture of digits, as well as the movement of the great toes of both feet.Results:After the surgery, all flaps in the 7 cases survived smoothly and the donor sites healed. All patients entered scheduled follow-ups postoperatively for 6 months to 2 years, with an average of 9 months. The flap showed an aesthetic appearance and excellent sensation, with a TPD of 3-6 mm, and satisfactory digit function. The donor site of the great toe fibular flap left linear scars only, without abnormality in range of motion and gait in walking. In addition, there were 5 in excellent and 2 in good according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Conclusion:Application of great toe fibular flaps of both feet is an ideal option for the simultaneous repair of pulp defects of two neighbouring digits, which can achieve good reconstructive results.
